Enabling secure e-mail using S/MIME
Sign
With your digital certificate (and the respective private key) you can send digitally signed e-mails. You only need to activate the signature setting in your e-mail software. Digitally signed e-mails are protected against unnoticed modifications en route and the recipient can be sure of the originator (unique assignment).
Encrypt
To send confidential information securely by e-mail, you need to have the recipient's digital certificate and to activate the encryption setting in your e-mail client. You can obtain the recipient's digital certificate from an e-mail signed by the recipient. If you don't have one, ask the recipient to send you a signed e-mail. His digital certificate is then available to your e-mail client after automatic or manual import.
S/MIME protects your
e-mails with the following methods:
Sign – to protect your
e-mail against tempering.
Encrypt – to keep the
e-mail content secret.
